			<h1>Go 语言结构体</h1>

<p>Go 语言中数组可以存储同一类型的数据，但在结构体中我们可以为不同项定义不同的数据类型。</p>

<p>结构体是由一系列具有相同类型或不同类型的数据构成的数据集合。</p>

<p>结构体表示一项记录，比如保存图书馆的书籍记录，每本书有以下属性：</p>

<ul>
<li>Title ：标题</li>
<li>Author ： 作者</li>
<li>Subject：学科</li>
<li>ID：书籍ID</li>
</ul>


<hr />

<h2>定义结构体</h2>

<p>结构体定义需要使用 type 和 struct 语句。struct 语句定义一个新的数据类型，结构体中有一个或多个成员。type 语句设定了结构体的名称。结构体的格式如下：</p>

<pre>type struct_variable_type struct {
   member definition
   member definition
   ...
   member definition
}
</pre>

<p>一旦定义了结构体类型，它就能用于变量的声明，语法格式如下：</p>

<pre>
variable_name := structure_variable_type {value1, value2...valuen}
或
variable_name := structure_variable_type { key1: value1, key2: value2..., keyn: valuen}
</pre>
<p>实例如下：</p>
<div class="example"><h2 class="example">实例</h2> <div class="example_code">

<h2>访问结构体成员</h2>

<p>如果要访问结构体成员，需要使用点号 <span class="marked">.</span>  操作符，格式为： </p><pre>结构体.成员名"</pre>

<p>结构体类型变量使用 struct 关键字定义，实例如下：</p>

<h2>结构体指针</h2>

<p>你可以定义指向结构体的指针类似于其他指针变量，格式如下：</p>

<pre>var struct_pointer *Books
</pre>

<p>以上定义的指针变量可以存储结构体变量的地址。查看结构体变量地址，可以将 & 符号放置于结构体变量前：</p>

<pre>struct_pointer = &amp;Book1
</pre>

<p>使用结构体指针访问结构体成员，使用 "." 操作符：</p>

<pre>struct_pointer.title
</pre>

<p>接下来让我们使用结构体指针重写以上实例，代码如下：</p>

首字母大写相当于 public。</li><li>
首字母小写相当于 private。</li></ul>
<p><strong>注意:</strong> 这个 public 和 private 是相对于包（go 文件首行的 package 后面跟的包名）来说的。</p>

<p><strong>敲黑板，划重点</strong></p>
<p>
当要将结构体对象转换为 JSON 时，对象中的属性首字母必须是大写，才能正常转换为 JSON。</p>

<p>示例一：</p>
<pre>type Person struct {
　　　Name string　　　　　　//Name字段首字母大写
　　　age int               //age字段首字母小写
}

func main() {
　　person:=Person{"小明",18}
　　if result,err:=json.Marshal(&amp;person);err==nil{  //json.Marshal 将对象转换为json字符串
　　　　fmt.Println(string(result))
　　}
}</pre>
<p>控制台输出：</p>
<pre>{"Name":"小明"}    //只有Name，没有age</pre>


<p>示例二：</p>
<pre>type Person  struct{
   　　Name  string      //都是大写
   　　Age    int               
}</pre>
<p>控制台输出：</p><pre>{"Name":"小明","Age":18}   //两个字段都有</pre><p>
那这样 JSON 字符串以后就只能是大写了么？ 当然不是，可以使用 tag 标记要返回的字段名。</p>

<p>示例三：</p>
<pre>type Person  struct{
   　　Name  string   `json:"name"`　  //标记json名字为name　　　
   　　Age    int     `json:"age"`
   　　Time int64    `json:"-"`        // 标记忽略该字段

}

func main(){
　　person:=Person{"小明",18, time.Now().Unix()}
　　if result,err:=json.Marshal(&amp;person);err==nil{
　　　fmt.Println(string(result))
　　}
}</pre>

<p>你可以定义指向结构体的指针类似于其他指针变量，格式如下：</p>
<pre>var struct_pointer *Books</pre>
<p>以上定义的指针变量可以存储结构体变量的地址。查看结构体变量地址，可以将 <span class="marked">&</span> 符号放置于结构体变量前： </p>

<pre>struct_pointer = &amp;Book1;</pre>
<p>使用结构体指针访问结构体成员，使用 <span class="marked">.</span> 操作符：</p>
<pre>struct_pointer.title;</pre>


<p>
定义结构体：</p>
<pre>
type Books struct {
   title string
   author string
   subject string
   book_id int
}

var book1 = Books {"Go 入门到放弃","yuantiankai","go系列教程",012231}</pre>

<p>例子：</p><pre>
var b *Books
  
b = &amp;Book1
fmt.Println(b)    //&amp;{Go 语言 www.runoob.com Go 语言教程 6495407}
fmt.Println(*b)   //{Go 语言 www.runoob.com Go 语言教程 6495407}
fmt.Println(&amp;b)   //0xc000082018
fmt.Println(Book1)    //{Go 语言 www.runoob.com Go 语言教程 6495407}</pre>
<p><strong>解释：</strong></p><p>
其实跟普通的指针是一样的，只不过这次是指定的结构体的指针，在上面的例子中：</p>
<pre>
var b *Books    //就是说b这个指针是Books类型的。
b  = &amp;Book1    //Book1是Books的一个实例化的结构，&amp;Book1就是把这个结构体的内存地址赋给了b，
*b             //那么在使用的时候，只要在b的前面加个*号，就可以把b这个内存地址对应的值给取出来了
&amp;b            // 就是取了b这个指针的内存地址，也就是b这个指针是放在内存空间的什么地方的。
Book1         // 就是Book1这个结构体，打印出来就是它自己。也就是指针b前面带了*号的效果。</pre>
<p>只有一个特殊的地方，尽管 b 所表示的是 Book1 对象的内存地址，但是，在从 b 对应的内存地址取属性值的时候，就不是 <strong>*b.title</strong> 了。而是直接使用<strong>b.title</strong>，这点很特殊，它的效果就相当于 <strong>Book1.title</strong>:</p>
<pre>fmt.Println(b.title)   //Go 入门到放弃
fmt.Println(Book1.title)   //Go 入门到放弃
fmt.Println(b.author)   //yuantiankai
fmt.Println(Book1.author)  //yuantiankai</pre>
<p>具体区别：</p>
<p>比如我们要写一个函数修改结构体里的一个值，那么我们需要将修改过后的值返回出来，然后再重新赋值，比如这样：</p>
<pre>package main
  
import "fmt"
  
type Books struct {
    title string
    author string
    subject string
    book_id int
}
  
func changeBook(book Books) string {   //把book对象传进来，返回的值是string类型的，也就是将被修改的值返回出来。
    book.title = "book1_change"
    return book.title
}
  
func main() {
    var book1 Books;
    book1.title = "book1"
    book1.author = "zuozhe"
    book1.book_id = 1
    var res = changeBook(book1)   //然后在外面拿到被修改的值
    book1.title = res        // 再重新赋值
    fmt.Println(book1)
}</pre>
<p>结果为：</p><pre>
{book1_change zuozhe  1}</pre>
<p>如果我们这样做，是行不通的，看如下代码：</p>

<pre>package main
  
import "fmt"
  
type Books struct {
    title string
    author string
    subject string
    book_id int
}
  
func changeBook(book Books) {  //这个函数没有返回值
    book.title = "book1_change"   //仅仅是修改了一下
}
  
func main() {
    var book1 Books;
    book1.title = "book1"
    book1.author = "zuozhe"
    book1.book_id = 1
    changeBook(book1)   //将book1传进去，本意是想修改book1里面的值
    fmt.Println(book1)
}</pre>
<p>结果为：</p>
<pre>  
{book1 zuozhe  1}   // 但是结果现实并没有任何修改。</pre>
<p>
<strong>但是有了结构体指针，就不是值传递了，而是引用传递（传递的是地址）了。</strong>就可以这么写了：</p>

<pre>package main
  
import "fmt"
  
type Books struct {
    title string
    author string
    subject string
    book_id int
}
  
func changeBook(book *Books) {  // 这个方法传入的参数一个Books类型的指针
    book.title = "book1_change"  //直接用指针.属性的方式，修改原地址的值。
}
  
func main() {
    var book1 Books;
    book1.title = "book1"
    book1.author = "zuozhe"
    book1.book_id = 1
    changeBook(&amp;book1)   //将book1这个对象的内存地址传进去，
    fmt.Println(book1)
}</pre>
<p>结果为：</p>
  
<pre>{book1_change zuozhe  1}  //成功修改了book1的值</pre><div class="comt-meta wrapper"><span class="comt-author"><a target="_blank" href="../note/67933">张三</a><div class="tooltip tooltip1"><p><i class="fa fa-user" aria-hidden="true"></i>&nbsp;&nbsp;&nbsp;张三</p><p><i class="fa fa-envelope" aria-hidden="true"></i>&nbsp;&nbsp;461***35@qq.com</p><p><i class="fa fa-external-link" aria-hidden="true"></i> <a rel="nofollow" target="_blank" href="https://www.cnblogs.com/haiguixiansheng/archive/2019/03/28/10613754.html">&nbsp;&nbsp;参考地址</a></p></div></span>1年前 (2021-11-04)</div></div></li><!-- #comment-## -->

GO语言结构体指针
 1. 没有特别，与一般指针一致。
 2. 调用成员变量可以使用 变量名.成员名、指针名.成员名 都可以，相当于自动解引用，不需要c语言的 -&gt; 符号。
 3. GO语言的自动解引用只支持到一级指针，多级指针就要至少手动解引用至一级指针。看来GO是做了，但是没完全做。
